In reality, a .prj file is just a text file, and thus can be viewed under notepad. For your situation, you can check your project file in this way, and make sure that all pathnames are correct. Another way I found to work around this is to start a new project, place all the files that you had in the previous project into the new project, and then save this new project under the old projects name, overwriting the old project. This seems to clear up the pathname errors. If these still do not work for you, drop me a line back. Thanks a lot.
